JPollution

JPollution is a pair of simple Java
programs that simulate a pollution sampling exercise. PollutionCreator
provides a blank map onto which hills and buildings can be drawn.
Buildings can generate one or both of ground water or airborne
pollution. The map can be saved, and can be loaded by the other
program in the package, PollutionSampler. This program displays the
map and provides an interface that lets the user take a set of samples
of the pollution, from which they can attempt to determine the
suitability of the land for various purposes.

An "Instructor's Manual" is available, which covers installation of the
programs and how to create and save a map. A "Student's Manual" is
also available, which covers loading a map and taking samples. A third
manual, the "Programmer's Guide" is documentation for those who wish to
modify or extend the code.

JPollution is released under the
GPL, which means
that you are permitted to modify and redistribute the program and its
source code. The main restriction is that if you distribute this
program or a modified version thereof, you must do so under the GPL.

Getting JPollution

JPollution is written in Java. To run the programs you will need a Java
Runtime Environment (JRE, also called a Java Virtual Machine, or JVM).
There may already be a JRE installed on your computer, but if not you
will need to download and install one. The official version is
produced by Sun, although there are
others. If you do not have Administrator priviledges on your computer
you will need to speak to your System Administrator to do this.
To find out if you have Java installed, and what version, follow the
instructions on this page.

Once you have a JRE installed, you need only download the programs for
the appropriate version from the links below, unzip them, and click on
their icons to run them. The Instructor's Manual and Student's Manual,
and a copy of the copyright and license notices are included. If you
are interested in modifying the code, you will also need the source
code and probably the Programmer's Guide. These are not needed for
normal use of the program.

The Programmer's Guide and source code (it's the same for all versions;
only the compiled version changes) can be downloaded here. The source
code is zipped up and includes a copy of the license and copyright
notices:

The Ibis picture used in this site is modified from the white
ibis pictured in A Pictorial
Atlas of the Port Lavaca Area. As per their
homepage , "Please feel free to
copy any images you like... We do request that if the image is
uploaded to a website...that proper credit is given." Proper credit and
thanks are hereby given. I would like to ask permission to use a
modified version, but I can't find an email address on the site.
